PHILIP A. BOVEN, MILAUKFE, VISCONSIN, ASSIGNOR OF ONE-HALF TO LOEFFELHOLZ St CO., OF SAME PLACE.

WATER-COCK.

EEP'ECIFICATION forming part of Letters Patent No. 312,077, dated February 10, 1885.

Application filed February 19, 18S-l.

To all whom, it may concern:

Be it known that I, PHILIP A. BOWEN, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful. Improvements in Vater- Cocks; and I do hereby declare that the following is a full, clear, and exact description thereof.

' My invention relates to fluid cocks or valves, 1c and will be fully described hereinafter.

In the drawings, Figure 1 is a central longitudinal'section of avertical cock embodying my invention. Fig. 2 is a similar view of a horizontal cock also embodying my invention. Fig. Sis a cross-section on line :c a, Fig.

2, looking toward the push-button G'.

A is the hollow stand that leads to the water-main.

B is a valve-chamber that is screwed into 2o the stand A.

B' is a piston, the head b of which is loosely tted in the barrel B2 of the valve-chamber. This piston has a hollow stein that projects through the valve-chamber, and is furnished with a valve, C', that is held in place by a nut, c. Through the piston B' a rod, d, is passed to receive a valve, D, that has its seat on the inner or lower end of the stem of piston B'. The bore in the stern of piston B' is considerably larger than the diameter of rod d, so that the water may iow up through the piston when valve D is opened.

E is a ferrule that is screwed into the barrel B2. This ferrule has an opening down through it to receive the rod, which opening for part of its depth is enlarged to accommodate a packing, ct, and recessed packing-cap a', through which rod d also passes. A thimble, G, is screwed onto ferrule E, and apush- 40 button, G', that slides in thimble G,is screwed onto the upper end of rod cl. This push-button is hollow and incloses a spring, g, that rests on cap a', and has a tendency to lift the rod d and close valve D.

The operation of my device is as follows: When the parts are in the position shown in Figs. 1 and 2 of the drawings, the water is shut off'. Now,to let the water on, the button G' is depressed, causing rod QZ to open valve 5o D. The water then rushes up through the piston, and, acting on its head b, depresses it (No model.)

and opens valrfe C, which remains open as long as button G is depressed; but as soon as button G' is released valveD closes,and the pressure from the main slowly closes valve O as the water above the piston-head nds its Way down between it and the barrel into chamber B, the water above ihe piston-head forming a cushion,that prevents any such sudden action ofthe valve as would cause the pounding that 6o is so objectionable in valves of ordinary construction. The lower rim of button G' is reduced in thickness, and is provided with a lug or lugs, g', above which a pin, g2, on the inside of thimble G may be made to engage by depressing the button and turning it slightly, and when this is done the valve is held open to permit a continuous flow of water through chamber B and spout H.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the chamber B, the piston B', the valve C, the rod d, having valve D at one end and push-button and closingspring at its opposite end, and the locking appliances g and g2, substantially as set forth.

2. The combination, with the chamber B and its barrel B2, of the recessed ferrule E, having packing a, the closing-cap a', and the 8o thimble G for receiving the exterior pushbutton and its spring, substantially as specified.

3. The combination of the thimble G, having pin g2, with the push-button G', having 85 locking-lug g', rod d, and spring g, substantially as shown.

4. The combination of the stand A, the charnber B, the recessed ferrule E, the packing a, the eXteriorly-threaded cap a within the en- 9o circling-thimble G, the main self-closing valve C, and the valve D, operable bythe rod d, substantially as described.

5. The combination, with the chamber B, of the piston B', the valve C, having its seat up- 95 on thelower end of the chamber B. the Valve D, having its seat upon the lower end of the piston B', the ferrule E, having capped packing-chamber, and the rod d, connected to the valve D, and adapted by the provision of the roo locking appliances g and g2 to be held either in an open or in a closed position.

6. The Combination, with the vchamber B, In testimony that I claim the foregoing I interioriy threaded at its outer end, of the ferhave hereunto set my hand, at Milwaukee, in rule E. exteriorly threaded at either end, the the county of Milwaukee and State of Wisthimble G, provided with pin g2, and engagoonsin, in the presence of two witnesses.
